Erbium oxide (Er2O3) evaporation material requires deposition source hardware compatible with its high melting point and density. The material must be processed using E-beam evaporation or thermal evaporation by RFQ with appropriate liners or boats to avoid contamination.
- Deposition Source Hardware: Use E-beam hearth with graphite, Al2O3, or BN liner, or tungsten, molybdenum, or tantalum boat for evaporation.
- Thickness Monitoring: Set the Z-ratio to 1.00 in the quartz crystal monitor for accurate film thickness measurement.
- Process Route Matching: Match the evaporation source hardware and process route to the material's melting point of 2350°C and film requirements.
How does the Z-ratio of 1.00 for Erbium Oxide (Er2O3) evaporation material simplify quartz crystal monitor calibration during thin-film deposition?
The Z-ratio of 1.00 indicates that Er2O3 has the same acoustic impedance as the quartz crystal sensor, meaning no tooling factor correction is needed for film thickness monitoring. This simplifies calibration in E-beam evaporation workflows, as the source lists a Z-ratio of 1.00, allowing direct thickness readouts without empirical adjustment.
What crucible or boat materials are compatible with Er2O3 evaporation material given its high melting point of 2350°C?
For E-beam evaporation, the source specifies compatibility with graphite, Al2O3, or BN liners. For thermal evaporation (available by RFQ), a W/Mo/Ta boat is recommended. These materials are selected to withstand the 2350°C melting point and maintain chemical inertness with Er2O3 during deposition.
What does the 'Pieces 325 mesh' specification mean for Er2O3 evaporation material, and how does it affect source loading?
The material is supplied as pieces that pass through a 325 mesh sieve, ensuring a fine, consistent particle size. This facilitates uniform loading into E-beam hearths or boats, promoting stable evaporation rates. The 99.9% purity and pieces form are explicitly specified for vacuum thin-film deposition workflows.
Erbium oxide (Er2O3) evaporation material supplied as 325 mesh pieces with 99.9% purity, designed for e-beam evaporation in vacuum thin-film deposition. The product's defined melting point (2350°C), density (8.64 g/cm³), and Z-ratio (1.00) support reproducible film growth, but thermal evaporation requires RFQ confirmation and specific hearth liners.
Positive
- High purity and defined physical form: 99.9% purity and 325 mesh pieces ensure consistent material identity and source loading for e-beam evaporation, with known melting point, density, and Z-ratio for process control.
- Multiple pack sizes for lab flexibility: Available in 25g, 100g, 500g, and 1kg pack sizes, allowing researchers to match material quantity to experimental scale without excess waste.
Trade-offs
- E-beam evaporation preferred; thermal by RFQ: E-beam evaporation is the recommended method; thermal evaporation requires special RFQ arrangement and use of specific hearth liners (graphite, Al2O3, BN) or refractory metal boats, adding procurement lead time and hardware constraints.
- Pre-order confirmation required for compatibility: Buyers must confirm deposition source geometry, certificate requirements, and shipment conditions before quotation, as the material is research-grade and requires validation for specific laboratory workflows.
